To all whom it may concern:

Be it knownthat I, JULns HLHIRnya citizen of the United States, residingat Sewickley, in the county of Allegheny and State of Pennsylvania, haveinvented anew and useful Improvement in Apparatus for Making Gas, ofwhich improvement the following is a specification. My inventionrelates'to apparatus for making gas. I p

The objects of my invention areto produce a simple and eflicient methodof making producer gas continuously,-and the production ofan' efficientapparatus adapted to I i cally disposed furnace, preferably circularcarry out said method. 7 p

In the accompanying drawings, I show a form of apparatus adapted to;carry out said method, in Which- Figure 1 is a diagrammatic view of theapparatus, the producer being shown in section. Fig. 2 is a plan view ofthe material charging mechanism and a section of a portion of thefurnace. Fig. 3 is a plan View of the cap.

In carrying out my improved method, T charge finely divided carbonaceousmaterial admixed with air into a closed chamber, ignite the same andadmit sufficient air to convert the material into carbon dioxid, andcontinue to so heat the furnace until the refractory lining of thefurnace is highly incandescent or almost in this condition, the volumeof air is reduced until only suflicient is admitted to convert saidmaterial to carbon monoxid. 'Steam or other form of moisture is admittedat a point of highest temperature in said furnace which subserves thetwo fold function of controlling the temperature and enriching bydisassociating hydrogen therefrom the gas evolved. The carbonaceousmaterial admixed with air is charged into the chamber under pressuretangentially. to the walls thereof whereby the material under ressure isgiven a circulatory movement an caused to contact or impinge upon theincandescent or highly heated walls of said chamber whereby any freecarbon therein adheres to said walls and remains thereon in an incandescent state, the force and direction given the incoming gases causingthe same to assume a vortex shape in its ascent and permitting anycarbon dioxid that may be the walls of said chamber.

evolved to be converted to carbon monoxid by contact with theincandescentcarbon on The. peculiar circulatory movement of the gasesserves to bring the highly heated g'ases'in constantcontact. withincoming material quickly gasimonoxid gas is conveyed from the :upperend of theproducer and readmitted with the carbonaceous material and airat the lower end thereof forjthe purpose of drying the carbonaceousmaterial without introducng any excess oxygen.

. Referring to said drawings, 1- 1s a, vertiin cross section. Theinterior of said furnace is divided lntoltwo compartments, 2

'60 fying the samepA' portion of the carbon and 3, the lower one, 2, ofwhich is'preferably circular in cross section, and is provided withan'openi'ng 4- which is, disposed tangentially relatively to the axis ofthe chamber, whereby when finely divided carbonaceous material ischarged intosaid I chamber it is caused to travelin a circu1atory pathso that the highly heated gases thereof meet the incoming material andraise the temperature thereof very considerably, and vortex like'the'gas ascends toand passes through the opening 6 into chamber 3, and isconveyed through pipe 6 to any suitable gas receiver (not shown);

A portion of gas passing from said chamher 3 through pipe 6 may be takenfrom said pipe 6 through pipe 7 and discharged into the fan, 8, where itserves to dry said material before the same is charged into the chamber2. A valve 9 in said pipe 7 controls the admission of'said gas. Aflcap10 in which passages 11, '11 are formed is placed immediately over saidopening 5, at though checker work orlother form of re- ,t-ardent maybeused to prevent the escape of fneecarbon, if any might be in the carbon'monoxid admitted to chamber 3. Ata

point in chamber 2 where the highest tenr the chamber pera ture isattained, a. e.', where it begins to contract a series of steam jets 12enter for the purpose of regulating or controlling the temperature ofsaid chamber, whereby the usual refractory materials may be employedinthe construction of the furnace, otherwise without the introduction ofthe steam. the temperature attained at this point in the furnace wouldquickly destroy the most highly refractory materials. The introduo tionof the steam at this pointby disasseciating hydrogen therefrom serves toproduce a better quality of gas than is usually obtained.

The apparatus herein referred to is broadly claimed in application S. N.465,424, filed Nov. 30, 1908; and the'process broadly in application543,726 filed Feb. 14, 1910.

The gas evolved may be taken oflz' through the opening 13 in the top ofthe producer instead of through pipe 6, andthe slag from. the impuritiescontained in the material is removed through the opening 14'.

The orifice 4 for the admission of carbonaceous material is disposed. ata tangent to the Walls of the chamber 2 and is connected with anysuitable fan, 8, for reducing the material to a finely divided state,and means for admitting thereto air under pressure.

Having described my invention, what 1 claim and desire to secure byLetters Patent is 1. In a device for making gas, the combination of twocommunicating chambers one above the other, an orifice tangent to thewalls and directed into the lower chamber to admit gas forming material,means to admit moisture to sald lower. chamber at a point near the topthereof, a cap located at the opening between said chambers havingpassages therein, a gas off-take from said upper chamber, means toconvey a part of said gas to the gas forming material, and means toforce said admixture into the lower chamber.

2. In a device for making gas, the combination oftwo chambers separatedfrom each other by a partition, an opening in said partitioni from oneof said chambers to the other, -a cap located directly in line with saidopening, means for supply of gas forming material to one of saidchambers, a gas off-take from the-other of said chambers, and means forconveying a portion of said gas to said means for supply of gas formingmaterial.

In testimony whereof, I have hereunto signed my name in the presence oftwo subscribing witnesses.
